IMPROVEMENT IN FOUNTAIN-PENS.

Specification forming part of Letters Patent No. 106,987, datedSeptember 6, 1870.

.To all 'whom fit may concern Be it known that I, GUsrAV A.. BECKER, ofSeymour, in the county of New Haven and State of Connecticut, haveinvented a new and useful Improvement in Fountain-Pens; and I do herebydeclare that the following is a full, clear, and exact descriptionthereof, which will enable others skilled in the art to make and use thesame, reference being had to the accompanying drawing, forming part ofthis specication, in which- Figure 1 is a longitudinal section of myimproved fountain-pen. Fig. 2 is a det-ail side View of the piston-rod.Fig. 3 is a side view of the cap that covers and protects the pen, partbeing broken away to shor the construetion.

Similar letters of reference indicate corresponding part-s.

My invention relates to fountain-pens; and consists in certainimprovements, which will be rst described in connection with all that isnecessary to a full understanding thereof, and then clearly specied inclaims.

A is the handle or holder of the pen, which is made tubular in form, andhas a plug, B, fitted closely into its upper end. The plug B isperforated for the passage of the piston-rod, and upon its outer end iscut a screw-thread to receive the cap C, which is screwed upon it. Inthe side of the screw-cap C is formed a small hole, c, so arranged thatwhen the cap is partly screwed on the air may pass into the interior ofthe tube A, but when the said cap is screwed down the hole c will comebelow the upper end of the plug` B, as shown in Fig. l, and prevent theentrance of air.

D is the supply-pipe, which is screwed into a screw-hole formed in thelower end of the handle A. The upper part of the pipe D is perforated,to allow the ink to pass down said perforations, passing out through themiddle part of the side of said pipe. The lower part of the pipe D isformed into a tongue, d', to conduct the ink from the outlet to thepoint ofthe penE. The penE is inserted in a curved or circular crease orslot, a', formed in the solid stock ofthe lower end of the handle A, sothat there can be no leakage around the pen.

F is a spring, the upper end of which is secured to the pipe D by arubber band or ring, G, slipped over the said spring and pipe, as shownin Fig. 1. The lower end ofthe spring rests against the point of thepen.

H is a small rubber tube, slipped over the spring F in such a positionas to rest upon the discharge-orifice of the pipe D, against which it isheld by the spring F. When the point of the pen is sprung back inwriting, the elasticity of the spring F raises the rubber ll away fromthe discharge-orifice of the supplypipe D, allowing the ink to How tothe pen.

l is a piston, fitted into the interior of the tubular handle A, andwhich has a screw-hole formed in it to receive the end of the pistonrodJ. A small perforation leads from the said screw-hole to the lower sideof the piston, toallow the air to pass through it when the piston-rod isdetached.

K is a cap, which is placed upon the lower end of the tubular handle Awhen the pen is not in use, to prevent the accidental discharge of ink.

To ill the handle A with ink, the screwcap C is removed, the' piston-rodJ is inserted and screwed into the piston I, and a pin or other smallarticle is inserted under the softrubber tube H, to keep thedischarge-orifice of the pipe Dl uncovered. The piston-rod is then drawnupward, filling the handle with ink. The pin is then removed, the rodscrewed out, an d the screw-cap C replaced and screwed partly down, andthe pen is ready for use.

Having thus described my invention, l claim as new and desire to secureby Letters Patentl. The arrangement with respect to tube A of aperturedcap C c', perforated plug B, and threaded perforated piston I, as andfor the purpose described.

2. The arrangement of rubber tubes (l ll and spring F with respect tothe supply-pipe D, as and for the purpose described.

GUSTAV A.. BECKER.
